Canadian cops use a helicopter, night vision and dogs to track down teenage thieves

It was supposed to be their very own Ocean's Eleven but it ended up becoming a scene out of Scooby Doo.
Three teenagers were left red-faced when their cunning scheme to steal candy from an amusement park was thwarted by police - who used dogs and a helicopter to track them down.
The crime caper started on Saturday when security guards at Canada's Wonderland in suburban Toronto called police to say they'd spotted three masked intruders.
The York Regional Police helicopter arrived and used its thermal imaging camera to scan the park.
Footage shows the three teens trying to hide from officers - but their white heat signatures mean they all stand out like a sore thumb against the black backdrop.
The helicopter then directs four officers on the ground, one of whom has a dog, to arrest the hapless trio.
The pilot says: 'I've got two, maybe three people huddled down near a tree. I've got one laying down, one crouched down. There's another heat source but I don't know if it's the third person or not.'
The teenagers, two 16 and one 15, were arrest for stealing an undisclosed amount of candy.
They were given a stern warning and ordered to take part in a community service programme.
In a statement police said: 'The youths were cooperative with police and were remorseful for their actions.'
Constable Andy Pattenden told CBC News Toronto that the kids 'definitely learned a lesson on that night'.
He added: 'They were probably scared out of their minds when they heard the helicopter and dogs hot on the trail.'
The video has sparked plenty of debate about whether the show of force was appropriate for arresting three trespassing teens.
Ryan Gillespie posted on the video: 'I still don't see how arresting 3 teens took the combined efforts of park security staff, three police officers, a helicopter, a tracking dog, a pilot and a co-pilot.
'It's a fenced in area with CCTV everywhere. This was an overreaction by the police and results don't justify the costs.'
Police however defended their actions, saying the helicopter was already in the area and that 'while it was only a theft of candy, it came into us a little differently'.
